Title: Coating process
Inventor: OWEN JOHN BRYN
IPC: C08J7/052
Filed: 1964-02-21
Abstract: Shaped articles composed at least in part of hydrophobic polymeric material are coated by applying to the article together or in separate steps (a) a polymeric substance containing in each molecule at least one reactive-OH group and (b) a halogeno-triazine in an amount of from 0.05 to 50% of the weight of the polymeric material and (c) an inorganic alkaline agent, and permitting the polymeric substance and the halogenotriazine to react with each other.  The shaped article may be obtained by e.g. casting, moulding or extrusion and may be sheets, foils and films. Hydrophobic polymers mentioned are polyethylene, polyesters such as poly ethylene terephthalate, polymers and copolymers of acrylonitrile, cellulose esters such as cellulose triacetate. Polymeric substances for the coating include natural and synthetic polymers such as: polyvinyl alcohol which may be partially esterified; alginic acid and its water soluble salts such as sodium alginate; starch and starch derivatives such as starch dextrins and starch ethers for example hydroxypropyl starch; cellulose ethers such as methylcellulose, hydroxyethyl cellulose, hydroxypropyl methyl cellulose; tannic acid; condensates of polyols such as glycerol and mannitol, with alkylene oxides.  The halogenotriazine compounds may be water soluble due to the presence of solubilising groups such as sulphonic acid, carboxylic acid salt, quaternary ammonium non-ionic groups, coloured or non-coloured, e.g. sodium 2-(2, 6-dichloro-1, 3, 5-triazin-2-yl) aminonaphthalene-6-sulphorate, sodium 1-(4, 6-dichloro-1, 3, 5-triazin-2-yl) aminonaphthalene-5-sulphonate, sodium-(4, 6-dichloro-1, 3, 5-triazin-2-yl) aminoethane sulphonate, sodium 1, 4-bis (chloro-6-methoxy-1, 3, 5-triazin-2-yl) amino benzene-2-sulphonate, 1-amino-4-4\sv-(4, 6-dichloro-1, 3, 5-triazin-2-yl) amino-3\sv-sulphoanilino-anthraquinone-2, 5-disulphonate, 3-(4, 6-dichloro-1, 3, 5-triazin-2-yl) aminophenyltrinethlyammonium bromide.  The reaction may be accelerated by heat.  The coated articles have an increased moisture absorbency, a a reduced tendency to acquire electrical charges, and films may have improved heat-seal-ability.

Title: Improvements in and relating to coin-freed prepayment meter
IPC: G07F15/06
Filed: 1935-03-11
Abstract: 455,213. Prepayment mechanism for electricity meters. BRITISH ELECTRIC METERS, Ltd., and BROWN, R. T., Morden Road, Mitcham, Surrey. March 11, 1935, No. 7582. [Class 27] In a coin-freed prepayment electricity meter of the kind in which in addition to the cost of the commodity supplied, a fixed charge is made, e.g. for rent of the meter, this fixed charge continuing to accumulate even if no commodity is supplied, in order to provide for more than one revolution of the switch control member, the plane of action of the operative part of a single trip lever co-acting therewith is automatically altered. As shown applied to the switch operating gear described in Specification 362,158, [Group XXXVII], in which a trip lever w, Fig. 1, coacts with a cup z gapped at 2 to allow the lever w to enter the gap and open the switch when the cup is rotated to proper position, the cup z is provided with a projecting tongue 5 in the plane of the bottom of the cup, this tongue, when the cup reaches switch-tripping position, rotating a disc 7 by engagement with pins 6 thereon. A notch 9 on the disc 7 rocks a lever 4 pivoted at 4a and having at its lower end a cam-shaped flange 12 which engages a pin 13 projecting from the hub 14 of the trip lever w and slides the lever w axially into such a position that it can no longer co-operate with the rim of the cup z as in normal operation. This allows the cup z to make a further revolution past its zero or switch-tripping position to accumulate arrears of rent. In another construction, Fig. 3, the tripping lever 17 has a flexible part 16 and the control member 18 comprises a flanged disc 19, Fig. 4, the flange 20 of which is formed with a bent-back cam portion 24. Normally the nose of the lever 17 engages the periphery of the disc 19, when the switch is closed, but when the control member 18 reaches its switch tripping position, the cam 24 bends the trip lever so that its head 17 passes in front of the flange 20, and the control member can now rotate to accumulate arrears of rent without the member 17 being operative to hold the switch closed.

Title: Improvements in or relating to cooling arrangements for electric machines
IPC: H02K5/12
Filed: 1921-03-12
Abstract: 181,477. Arut³noff, A. March 12, 1921. Armatures and fieldmagnets, cooling; casings. -The cooling-liquid in a dynamo-electric machine is continuously pumped in a closed circuit from a chamber at one end of the machine through the hollow rotor shaft and in contact with parts of the stator to a chamber at the other end without touching the outer surface of the rotor, whereby fluid friction at the rotor surface is minimized. Fig. 1 shows the application to a vertical machine, of which Fig. 2 is a section on the line a, a. The shell 1 carries, by threaded collars 20, 21, the oil-well 2 and upper bearing-member 3, which together form a fluidtight casing. The oil stands at the level a, a when the machine is at rest and when it is running a pump 8 propels it up through the hollow shaft which it leaves by offset passages above the centri. fugal throwing-disc 12, the level in the casing falling to b, b. The descending oil passes through passages K<1>, Fig. 2, between the field coils, these passages being defined from the rotor bore by separating-plates 23. Ir the case of alternating- current machines having a continuous circular iror stator, vertical ducts in the iron provide the return path. The pump in the case of a thick shaft may be sunk in a recess in the shaft end instead of being external thereto, as shown, and in either case it is fitted with a filter grid. The well has a settling-chamber 19 such that the sediment cannot mix with the clean oil even if the machine be inverted. The lower bearing is lubricated by the cooling-oil and the upper one is closed by a stuffing-box 15 sealed by oil kept under pressure by a screw 16. In the form shown in Fig. 6, the frame 1 has end caps carrying bearings 3<a> which, together with tubular liners 32, define oil-chambers 30, 31 in the stator completely cut off from the rotor. The oil is carried by the pump 8 from the well 36, up the. passage 35, and through the shaft bore 7 and passage 33 to the chamber 30. It returns through the stator laminae or between the field coils back to the chamber 31 and through the pipe 34 to the well 36 from which the pipe 35 supplies the pump. This pipe has a closed upward extension 37 which remains filled when the machine is at rest and serves as an inlet for fresh oil. The bearing 3a is lubricated by cooling-oil through offsets 39 from the shaft bore, which oil also serves as a liquid seal to the pump suction chamber.
